Neem Oil affects over 400 varieties of insects and is an important part of an Integrated Pest Management (IPM) strategy. This foliar spray is 100% pure neem oil from the neem tree. It is a biodegradable and fast-acting insect bio-inhibitor. Simply mix 1/2 teaspoon neem oil with a quart of water (use a drop of dish soap to emulsify the mix) and spray on your plants' leaves. The oil is absorbed by the pests and interferes with reproduction and feeding for a steady decline in population. This 8-ounce bottle makes 24 gallons of solution.
